Love the mouse, but the battery wasn't lasting more than 3 days.
Here's a pic of the original battery (602030 300mAh 3.7V):

I bought a replacement battery from AliExpress:
902030 550mAh 3.7V JST 1.5mm 3pin
Here's a pic of the final result:

There's plenty of height clearance, but no wiggle room with length and width.
The most important tidbit is the polarity of the wires; I had to swap red(+) and black(-).
On the original battery (all black wires) you can see the P- and P+ indicators on the original battery circuit board. In summary, the "bottom" of the connector (on the mouse) expects a positive (red wire), middle is the sensor (yellow wire), top is negative (black wire).
The battery arrived with the red and black wires the other way around. I used the smallest flathead screwdriver to, very slightly, prop the plastic "prong" (where you see the three plastic 'prongs', not the flat side) of the red/black wire and gently pull them out. Take note of the wire's positioning (the metal bit). The top has a very tiny metal bump that "clips" against the plastic prong you lifted. Putting the wire back into the housing should be "like a glove"; no forcing.
Everything is working without issues so far. The Pulsar software is reporting the battery level, but can't be sure if it's accurate. I also haven't had a chance to measure how long the new and improved battery lasts.
Another tidbit, I tore the "ribbon" when taking the mouse apart.

The cable connects the side buttons. I found a replacement (no thanks to Pulsar support who told me to either pound sand because they wouldn't even hint on tech specs of the cable or pay to ship to Korea and wait months for it to get sorted which it wouldn't because me disassembling the mouse isn't covered under warranty [fair enough]).
The exact title of the cable I ordered is: "uxcell FFC Flexible Flat Cable 10 Pins 0.5 mm Pitch B Type 80mm". The most important specifications are:
- 10 Pins
- .5 mm pitch
- B Type
- 80mm (perfect length, but can go a little shorter if you must)
